In this world of distance learning, I would like to know if it is possible to invite a guest to a Conference on Canvas (Big Blue Button) who is not listed in the course.  My 'people' in the course consist of students, parent observers, support staff, et al.  I have used Conference for online meetings with students and adults listed, but would occasionally like to include another person in the conference who would not otherwise be added to the roster (for example an outside consultant, a counselor, a guest speaker, et al).  For confidentiality, I would much prefer to use Canvas Conference rather than Zoom, if it is a possibility.  Thanks in advance for your response.
